What to Expect from Book of Mrs Claus

Book of Mrs Claus is a Christmas-themed slot from Aurum Signature Studios, released in December 2021 and distributed through the Games Global network. It follows the classic 'book of' formula you might know from similar titles, but wraps the whole thing in a festive skin starring Santa Claus's wife. The game uses a standard 5-reel layout with 10 paylines.

If you have played any 'book slot' before, the structure here will feel very familiar. The book symbol acts as both the wild and the scatter, and the main attraction is a free spins round with an expanding symbol. What does set it apart slightly is the Hyperspins feature, which lets you respin individual reels for a price. The visuals are simple and cartoonish, giving the slot a cosy but somewhat dated feel.

Book of Mrs Claus RTP, Volatility and Max Win

The RTP for Book of Mrs Claus sits at 96.5%, which is above average for the 'book of' genre and a decent figure for UK players checking the stats before committing. The maximum win potential is 5,000x your stake, achieved when the screen fills entirely with the top-paying Mrs Claus symbol during the bonus round.

Volatility follows the standard pattern for book slots, meaning you should expect longer dry spells in the base game punctuated by the occasional bigger payout when you trigger free spins and land a good expanding symbol. It is not a low-variance gentle ride, so keep your bankroll expectations realistic.

Book of Mrs Claus Symbols and Paytable

The red Book symbol is the most important icon on the reels. It works as both wild and scatter, substituting for all other symbols to help complete winning lines. Landing three or more books anywhere in view triggers the bonus round and pays a scatter reward on top.

Premium symbols include three animal icons and Mrs Claus herself, who is the highest-paying symbol on the paytable. The premiums are worth between 75x and 500x your total stake for five of a kind. Below those you will find the usual set of royal card symbols, which pay less but appear more frequently.

During the free spins feature, the randomly chosen expanding symbol does not need to land on adjacent reels to pay out. Premium symbols only need two anywhere on screen to expand across the reels, while the lower-value royals require three. This is a key distinction that makes premium expanding symbols far more valuable.

Book of Mrs Claus Bonus Features Explained

The main bonus in Book of Mrs Claus triggers when you land 3, 4 or 5 book scatters anywhere on the reels. This awards an immediate scatter payout of 2x, 20x or 200x your stake respectively, plus 10, 12 or 25 free spins. Before the spins begin, one symbol is randomly selected as the special expanding symbol for the entire round.

The Hyperspins feature is available after every base game spin and lets you respin any individual reel as many times as you like. Each respin has its own calculated cost, which goes up if something valuable could land on that reel. It is primarily useful as a way to chase that third scatter when you already have two books showing. You cannot use Hyperspins during the free spins round, so it is purely a base game tool. In testing, the cost to land a third scatter came to roughly 7x the total stake, though this varies.

Is Book of Mrs Claus Worth Playing?

There are not many Christmas-themed book slots about, and making it about Mrs Claus rather than Santa gives Book of Mrs Claus a bit of novelty. Beyond the theme though, this is a straightforward 'book of' release that does not add any genuinely new mechanics. The 96.5% RTP is a genuine plus, sitting comfortably above the industry average.

The Hyperspins feature adds a layer of player choice, but it can get expensive quickly if you chase triggers too aggressively. If you enjoy the classic book slot formula and fancy a festive version with a solid RTP and 5,000x max win, it does the job. Just do not go in expecting anything that will reinvent the wheel.
